im hoping a tune and larger injectors as well as a 3.5 bar fuel pressure regulator will fix my problems

If you're only around 8psi I doubt that you're maxing out the 42lb injectors. I haven't been following this build religiously... have you upgraded your fuel pump at all?

I'm running 42lb injectors on my turbo 327i off of the stock fuel pump with one of the ebay t04e turbos, which I know is smaller, but I'm running it up to 12-13psi without any fuelling issues.
